Abstract (en)
The present invention provides a data centre cabinet, comprising a cabinet body, an oil distributor and a plurality of liquid distributors. The cabinet body is sequentially mounted with a plurality of server housings from high to low. A liquid distributor is provided above each of the server housings. The present invention also relates to a gravity spray system. On the one hand, as cooling liquid oil is concentrated in an oil distributor tank disposed above, the oil automatically flows along an oil passage under gravity, and there is no need to provide pressure in the oil passage, thus reducing the power consumption of an oil pump, improving the coefficient of performance (COP) of a heat dissipation system and reducing the overall PUE of a data centre. On the other hand, to solve the problem that the height differences between the servers in the cabinet caused by the top-down arrangement lead to inconsistent distribution quantity of the oil in a gravity oil distribution circuit, an oil quantity regulator in an oil distribution unit is used to ensure consistent flow rate distributed to each layer of server. The present invention is ingenious in design, rational in structure and innovative in method, breaks through the traditional cooling manner for large servers, has strong practicability and is convenient for popularization.
